ADCP bathymetry of Lake Michigan nearshore near Ogden Dunes/Burns Harbor, Indiana

Description

The US Army Corps of Engineers (USACE) is evaluating the placement of dredged material in the nearshore areas of Lake Michigan as a means to replenish sand at selected beaches. In order to elucidate the physical processes in the nearshore environment that transport and distribute sand to the beach, the USACE-Chicago District and the US Geological Survey (USGS) developed a plan for a beach nourishment study on Lake Michigan near Burns Harbor/Ogden Dunes, Indiana. In support of this effort, five bathymetric surveys with a boat-mounted Teledyne RDI 1200 kHz acoustic Doppler current profiler (ADCP) were completed in the study area. ADCP data were collected using WinRiverII and exported for post-processing in The Velocity Mapping Toolbox (VMT) (Parsons et al., 2013). A tide file of water surface elevations for each transect in each survey was derived from the nearest USGS gaging station (Portage-Burns Waterway at Portage, IN; gage number 04095090; USGS National Water Information System, http://dx.doi.org/10.5066/F7P55KJN) and used to convert the ADCP-measured depths into bed elevations with the Export Multibeam Bathymetry tool in VMT. The surveys occurred on the following dates: June 2, 2016, July 20, 2016, September 8, 2016; October 11-12, 2016, and November 15, 2016. These survey dates bracket a planned placement of dredged material in the study area that occurred between June 15, 2016 and July15, 2016. In addition to the planned placement of dredge material, an independent dredging barge was observed working in the study area on Sept. 8, 2016. Parsons, D. R., Jackson, P. R., Czuba, J. A., Engel, F.
